Following an architecture vision such as the Generic Component Model (GCM) architecture framework, health information systems for supporting personalized care have to be based on a component-oriented architecture. Representing concepts and their interrelations, the GCM perspectives system architecture, domains, and development process can be described by the domains' ontologies. The paper intro...

We have recently developed an object-oriented refinement calculus called rCOS to formalize the basic object-orient design principles, patterns and refactoring as refinement laws. The aim is of rCOS is to provide a formal support to the use-cased driven, incremental and iterative Rational Unified Process (RUP). In this paper, we apply rCOS to a step-wised development of a Point of Sale Terminal ...

Model-driven development finds its origin in a reframed version of Zachman’s Information Systems Architecture. This framework recognises levels of abstraction, which is not the same as levels of detail, in the systems development process. If the model-driven approach is applied in addition to object oriented analysis concepts, significant benefits are to be expected on the side of maintenance c...

This article analyzes the performance of vertical handover between UMTS and WiMAX networks by defining development architecture for supporting mobility between these two technologies. First, architectures and principles of operation of networks UMTS and WiMAX are detailed and compared. Then the main protocols of mobility are considered as support of handover between UMTS and WiMAX (802.16). Fin...

Modern information systems are considered as collection of independent units called services that interact with each other through the exchange of messages. This paper focuses on interactions from a more centralized or global perspective (i.e. choreography), validates the underlying approach to model interactions, and discusses how choreographies can be executed with an established agent-orient...

Stuart Schreiber is an Investigator at the Howard Hughes Medical Institute and Morris Loeb Professor in the Department of Chemistry and Chemical Biology at Harvard University. His chemical biology research, which uses small molecules derived from diversity-oriented synthesis, observational screens and information science, has uncovered principles that underlie information transfer and storage i...

The rapid development of big data and artificial intelligence has an increasingly profound impact on society business, the demand for talents in market changed dramatically. In context new business forms, this paper analyzes demands enterprises by conducting surveys enterprises, re-examines orientation training application-oriented universities, puts forward that needs to follow people-oriented...

Agent-based, decision-support systems provide human decision-makers with a means of solving complex problems through collaboration with heterogeneous collections of both human and computer-based expert agents. Over the past decade the Collaborative Agent Design (CAD) Research Center has developed several proof-of-concept and production-oriented agent-based, decision-support systems for both com...
